SECTION 2 INSTALLATION

D. INSTALLING FEED ROLL

Lower Feed Rolls

1. Release the tension lever on the pressure roll bogey and ip up to access the drive rolls

2. Remove the lower feed roll retaining knobs.

3. Separate the feed roll from the gear pin axle and slip the new feed roll on the gear shaft, engaging the gear pins.

4. Reinstall the feed roll retaining knobs.

Upper Feed Rolls

1. Release the tension lever on the pressure roll bogey and ip up to access the drive rolls

2. Remove the upper feed roll retaining knobs by turning knob 1/4 turn and pulling axle straight out.

3. Separate the feed roll from the gear pin axle and slip the new feed roll on the gear shaft, engaging the gear pins.

4. Reinstall the feed roll retaining knob and axle.

E. INSTALLING SPOOL OF WIRE

1. Remove“S-pin”clipfromspindle.

2. Position the spool of wire so that when it is placed on the spindle, wire will be drawn to the feed roll from the bot tom

of the spool. The spool should be held so that the index hole on the spool will engage the pin on the spindle.

3. Slide the spool onto the spindle until it engages the spindle pin. Lock in place with the S-pin clip.

4. Loosen the brake screw in the center of the spindle hub, then tighten it just enough to prevent coasting of the spool

when wire is drawn from it. Too much pressure will load the wire feed motor unnecessarily. Too little pressure will

permit the spool to overrun, causing the wire to come loose and tangle.

Do not allow metal-to-metal contact between the wire feeder chassis and a metal surface connected

in any way to a welding ground. With such contact, a poor welding ground connection may create

a dierence in potential that sends part of the weld ing current through the safety ground wiring in

the control cable and wire feeder, resulting in burnout of that wiring and/or damage to wire feeder

circuitry. If the safety ground burns out, the opera tor may be exposed to electrical shock hazard.

NOTE

The top roll arms are designed to equalized the pressure of each driven feed roll in order to optimize wire

feeding performance. DO NOT attempt to operate this drive system with only two drive rolls instead of the

recommended four drive rolls. Poor wire feed operation will result and possible damage and premature

wear of the gears driving the feed rollers.
